Today we learned about factorial notation into perms/coms(permutation/combination). Permutation means-an ordering of objects in which order matters(ie. makes a diffrence) ex. phone number, locker permutation, postal codes, etc. a combination means- an ordering of objects in which ORDER doesn't matter, ex. card hands, pizza toppings, committee membership(all members the same). the formula for perutation is nPr and the formula for combination is nCr which means n objects combined r at a time nCr=n!/(n-r)!*r!

Today we learned about probability. We have to know how to put things into fractions, decimals, percentages, and words. Our calculators make fractions easy by pressing the math button and selecting the frac option. Also Pascals triangle plays a key role in probability. Each top two numbers added together makes the number below it.
We also recieved an excercise booklet.

Today I decided my Vectors Project would consist of the resultant vector being from where I live to the Co-op. We also were given some time to work on our excercises.
